Module Network Input Messages - ABS Module

Broadcast Message	Originating Module	Message Purpose
Accelerator pedal position	PCM	The ABS module uses accelerator pedal position information for correct operation of the traction control, ESC and hill start assist systems.
Ambient air temperature	PCM	This message informs the ABS module of the current ambient air temperature. This information is used for various stability control system operations and system diagnosis.
AWD status	AWD relay module	This message informs the ABS module of the current AWD system status; open by command, inactive, failure, warning, disabled, fully locked by command, torque limited by external device or under external torque control. This information is used for traction control and ESC operation.
AWD torque output	AWD relay module	This message informs the ABS module of the current AWD system torque output. This information is used for traction control and ESC operation.
Brake on-off switch	PCM	This message informs the ABS module the driver has pressed the brake pedal. This message is also used by the ABS module to check the brake pressure sensor located inside the HCU.
Brake precharge request	PCM	This message informs the ABS module either the adaptive cruise control or the collision avoidance system requires the brake hydraulic system to be pressurized in anticipation of a severe braking event.
Clutch pedal position	PCM	This message informs the ABS module the driver has pressed the clutch pedal. This message is used by the ABS module for the hill start assist system.
Cruise control status	PCM	This message informs the ABS module of the current status of the cruise control system; off, denied, standby denied, standby, active que assist or active.
Deceleration request	CCM	This message is used to request vehicle deceleration by the ABS module for either the adaptive cruise control system or the collision avoidance system.
Drive module switch	GFM2	This message informs the ABS module of the current, driver selected vehicle mode; Normal, Sport, Track or Drift. The ABS module adjusts the thresholds for anti-lock braking and stability control system intervention depending on the drive mode selected.
Drive wheel torque	PCM	This message provides the ABS module with the current amount of torque being output to the drive wheels. This information is used for traction control and ESC operation.
Driver request traction control mode	BCM	This message informs the ABS module the driver has deactivated the traction control system.
Door ajar	BCM	This message informs the ABS module of a change in door (driver or passenger, front or back), hood or liftgate status; closed or ajar. The ABS module modifies stability control calculations based on vehicle occupancy.
Engine output torque	PCM	This message provides the ABS module with the current amount of torque being output from the engine. This information is used for traction control and ESC operation.
Engine RPM	PCM	This message provides the ABS module with the current engine RPM. This information is used for traction control and ESC operation. This information is used for the hill start assist system.
Ignition key type	BCM	This message informs the ABS module of the type of ignition key being used; standard, MyKey®, read failure, key unknown or key invalid. The ABS module adjusts traction control operation if a restricted MyKey® is used.
Hill start assist neutral	PCM	This message informs the ABS module if the transmission is in NEUTRAL or not in NEUTRAL. The hill start assist system does not operate when the transmission is in NEUTRAL.
Hill start assist status	BCM	This message provides the ABS module with the current driver selected hill start assist setting; Off, Auto or Manual.
Odometer value	BCM	This message provides the ABS module with the odometer value in kilometers.
Parking brake status	BCM	This message provides the ABS module with the current parking brake status; activated or not activated. This information is used for the hill start assist system.
Power mode	BCM	This message provides the ABS module with the current vehicle power mode; key out, key recently out, key approved, post accessory, accessory, post ignition, ignition ON, running or cranking.
Power pack status	PCM	This message provides the ABS module with the current engine status; init, awake, ready, prestarting, start in progress, running, running_start in progress, running_remote started and after run.
Power steering mode	PSCM	This message informs the ABS module of the current driver selected power steering mode; Normal, Sport or Comfort. The ABS module adjusts the thresholds for anti-lock braking and stability control system intervention depending on the drive mode selected.
RCM serial number	RCM	The ABS module stores the RCM serial number and verifies the serial number when the vehicle is started or the ignition is set to RUN or ACC. Over time, the ABS module learns the offset of the stability sensors inside the RCM. When a new serial number is found and the IVD Initialization procedure is carried out using a diagnostic scan tool, the ABS module resets the offset number learned for ESC.
Reverse gear status	PCM (manual transmission only)	This message informs the ABS module when the transmission is in reverse gear, this is used for the hill start assist system and the ESC system. The hill start assist system works in forward and reverse gears. The ESC system does not operate when the transmission is in REVERSE.
Selector lever (PRNDL) status	TCM (automatic transmission only)	This message informs the ABS module when the transmission is in reverse gear, this is used for the hill start assist system and the ESC system. The hill start assist system works in forward and reverse gears. The ESC system does not operate when the transmission is in REVERSE.
Steering angle information	SASM	The ABS module receives several steering angle messages (steering angle sensor status, angle counter, velocity, rotation direction, angle from center and number of rotation) and uses these messages for operation of the ESC.
Traction control configuration	BCM	This message informs the ABS module of the current MyKey® traction control status; selectable or always on.
Transmission output torque	TCM (automatic transmission only)	This message provides the ABS module with the current amount of torque being output from the transmission. This information is used for traction control and ESC operation.
Transmission shift active	PCM	This message informs the ABS module the transmission is currently changing gears. This information is used for traction control and ESC operation.
Torsion bar information	PSCM	The ABS module receives several EPAS torsion bar messages (speed, direction and turning force) and uses these messages for operation of the ESC.
Vehicle configuration data	BCM	This message provides the ABS module with the current optional and configured items such as tire size, axle ratio, manual or automatic transmission, keyless entry and VIN.
Vehicle vertical acceleration	GFM2	This message provides the ABS module with the current dynamic suspension height sensor information. This information is used for vehicle stability control.

Module Network Input Messages - SASM Module

Broadcast Message	Originating Module	Message Purpose
